It was completed in 1869 (begun about 1865, but that's not exact).
When the First Tanscontinental railroad was built, all the smoke came to where the Native Americans lived. They called the train the 'Iron Horse".
The Transcontinental Railroad connected the east coast of the United States with the west coast. Previous to the completion of the railroad the only way to cover the distance was on horseback which could take several months.
It is often argued that the transcontinental railroad increased the national GNP, but an economic study shows that the GNP would have remained the same without the railroad, but it would have been concentrated in the East.
The First Transcontinental Railroad opened for traffic on May 10, 1869.
